Hello Haxor!
First, I would like to clarify that I live in a country where we use commas and not dots on the numeric keypad.
Now on to my problem: I played Hardware Tycoon version 0.2.12 in the browser and I was able to price my CPUs normally with the comma, however I downloaded this same version for Windows 10 Home 64bit and the numeric keypad comma doesn't work in my prices , therefore, I need to use the alphabetical keyboard dot, and that becomes a bit annoying. I like to use my laptop's numeric keypad for pricing and I don't understand this discrepancy from the browser version to the 64-bit Windows version. I appreciate any response from you.
